Intrusion Detection problem is one of the most promising research issues of Information Security. The problem provides excellent opportunities in terms of providing host and network security. Intrusion detection is divided into two categories with respect to the type of detection. Misuse detection and Anomaly detection. Intrusion detection is done using rule based, statistical, and soft computing techniques. The rule based measures provide better results but the extensibility of the approach is still a question. The statistical measures are lagging in identifying the new types of attacks. Soft computing techniques offer good results since learning is done using the training, and during testing the new pattern of attacks was also recognized appreciably.
